ncussion Syndrome (PCS). SIS occurs when a second blow to the head happens before an athlete has completely recovered from a concussion. This second impact causes the brain to swell, possibly resulting in brain damage, paralysis, and even death. PCS can occur after a second impact. PCS can result in permanent, long-term concussion symptoms. The risk of SIS and PCS is the reason why no athlete should be allowed to participate in any physical activity before they are cleared by a qualified health care professional. Recovery A concussion can affect school, work, and sports. Along with coaches and teachers, the school nurse, athletic trainer, employer, and other school administrators should be aware of the athlete’s injury and their roles in helping the child recover. During the recovery time after a concussion, physical and mental rest are required. A concussion upsets the way the brain normally works and causes it to work longer and harder to complete even simple tasks. Activities that require concentration and focus may make symptoms worse and cause the brain to heal slower. Studies show that children’s brains take several weeks to heal following a concussion. www.healthyohioprogram.Ãƒ…Ã‚ÂÃƒ…½Ãƒ‡€ÃƒÂ¬Ãƒ‡€Ãƒ…Ã‚ÂÃƒ†‰Ãƒ†‰/concussion
